1. REFLECTIONS, ROTATIONS AND TRANSLATIONS

2. Reflections

3. OBJECT IMAGE Reflect the triangle in the mirror line. The line joining a point to its image is always at right angles to the mirror line.

4. OBJECT IMAGE Reflect the shape in the mirror line. The line joining a point to its image is always at right angles to the mirror line.

5. OBJECT IMAGE Reflect the shape in the line y = 5. First draw the mirror line. y x 2 2 4 4 6 6 0 0 8 8 10

6. Rotations

7. Rotate the triangle 90 o clockwise about the given point.

8. Use tracing paper for rotations.

9. Rotate the triangle 90 o clockwise about the given point. Object Image

10. Rotate the triangle 180 o about the given point.

11. Use tracing paper for rotations.

12. Rotate the triangle 180 o about the given point. Object Image

13. Translations

14. A translation is a transformation that ‘slides’ a shape from one place to another. IMAGE OBJECT In a translation each point on the original shape moves the same distance and in the same direction. This is a translation of. The top number is the movement in the x direction. positivenegative The bottom number is the movement in the y direction. positive negative 4 5
